I got a new puppy a little over a week ago. When I brought her home she was roughly 8 weeks old (can't tell for SURE because she was from a shelter and the pups weren't born there). She is a German Shepherd (mix, maybe). Her mother was also at the shelter and she definately looked to be a pure breed GSD, but no idea about the father. When I brought her home she was almost completely tan, except for a black mask and a little black on her tail. Now her entire back is turning black and it is moving down her sides a little bit. If this color gets a little darker she will look an aweful lot like her mother (or any other GSD). I am just wondering if it is normal for a puppy's colors to change a little as they mature?
